No. 17/651,363, filed Feb. 16, 2022, entitled “Stabilized Active Oxygen-Generating Antiseptic Compositions, Irrigation Solutions, and Implants,” which claims the benefit of and priority to U.S. Provisional Patent Application No. 63/150,241, filed Feb. 17, 2021, entitled “Stabilized Active Oxygen-Generating Antiseptic Compositions, Irrigation Solutions, and Implants,” the disclosures of which are incorporated by reference in their entirety and made part of the present U.S. non-provisional utility patent application for all purposes.

FIELD OF THE INVENTION

This application is directed to stabilized active oxygen-generating antiseptic compositions, irrigation solutions, and implants. More specifically, this application is directed to stabilized active oxygen-generating antiseptic compositions, irrigation solutions, and implants derived from sulfates, persulfates, and, in some embodiments, amino acids.

BACKGROUND OF THE INVENTION

Wound lavage is a key aspect of reducing post-operative infections. Well known for over a century, intra-operative wound irrigation reduces rates of infection via removal of debris, reduction of bacterial load, reduction of metabolic waste, and removal of wound exudate.

Wound lavage is described by three primary variables: the volume of the irrigation fluid; the mechanism/timing of delivery (pressure and distribution); and the composition of the irrigation fluid itself. The composition of the irrigation fluid is typically selected so as to present antibiotic, surfactant, or antiseptic properties. Antibiotic irrigation fluids may be quite effective, particularly where a specific antibiotic for an identified microorganism which is not drug resistant is applied. However, antibiotic irrigation fluids tend to be high cost, are subject to and may lead to development of antibiotic resistance, and are typically characterized by slow onset to action. Surfactant irrigation fluids are problematic in that they may have detrimental effects on osteoblast/osteoclast cell lines, and it is known that bacterial counts may significantly rebound following lavage. Antiseptic irrigation fluids have potentially excellent characteristics for lavage, including for orthopedic and general surgical site infection. However, known antiseptic irrigation fluids are either deficient in anti-microbial activity or have detrimental effects, such as causing damage to live tissue, which are unacceptable.

The current standard wound lavage in use, which was invented in 1955, is povidone-iodine, which has equivocal benefits, limited data, and known metabolic toxicity. Indeed, a systematic review and meta-analysis published in March 2020 shed doubt on the efficacy of povidone-iodine, revealing that in seven studies with 31,213 TJA cases there were no differences in post-operative infection rates between povidone-iodine and non-povidone-iodine lavage groups. Similarly, recent Mayo Clinic case series reported no risk reduction effect of povidone-iodine lavage on post-operative infection in a large combined series of more than 10,000 THAs and TKAs. Despite the lack of evident effectiveness, povidone-iodine also has significant negative effects, including inhibiting cell migration and survival of osteoblasts, fibroblasts, and myoblasts. At all tested concentrations, povidone-iodine, even at a dilute 0.35%, produces a pronounced chondrotoxic effect when used for more than 1 minute, necessitating washing out of the application site following use. Topical application of povidone-iodine prior to wound closure is associated with significant increases in serum iodine level.

Triple salts are known to disassociate highly reactive oxygenated species when exposed to elevated moisture levels and may approximate the effects of naturally occurring oxidative bursts. However, triple salts possess only limited antimicrobial activity, due in part to the very slow rate of solid to liquid transformation of triple salts when exposed to elevated levels of moisture. Further, triple salts have limited shelf life and may contain hazardous impurities, including, but not limited to, irritants.

Accordingly, it would be desirable to provide antiseptic compositions which overcome the above-described deficiencies.

Microbes produce a biofilm matrix consisting of bacterial extracellular polysaccharide polymer protecting the bacterium within. A chronic wound, such as a surgical wound, is a wound that is arrested in the inflammatory phase of wound healing and cannot progress further. Over 90% of chronic surgical wounds contain bacteria living within a biofilm. Disruption of biofilm extracellular matrices and eradication of surgical biofilms is a major healthcare challenge. Depolymerization of biofilm protective polysaccharide polymer structures by selective oxidation of glycosidic linkage to form glucose monomer to form glucose monomer, and eradication of bacteria within the biofilm may be achieved in the present invention by an active oxygen release mechanism.

Inventive stabilized active oxygen-generating antiseptic compositions and irrigation solutions may remain on a wound site and deliver active oxygen for more than three days. Inventive stabilized active oxygen-generating antiseptic compositions and irrigation solutions may provide effective tissue regeneration by active oxygen and extracellular matrix formation in liquid for cell attachments. Low concentration of active oxygen from stabilized active oxygen-generating antiseptic compositions and irrigation solutions may delver unmet properties to all types of wounds, including, but not limited to, surgical wounds and procedures, nostrils and oral sites, colorectal surgical sites, traumatic wounds, burns, lacerations, diabetic wounds, combat wounds, acute wounds, and chronic wounds.

As used herein, “active” oxygen refers to an oxygen species which is less stable than, and hence more active than, ground state triplet 02. Active oxygen species include, but are not limited to, singlet 02, ozone, superoxide, and peroxide.

The amino acid of the reaction solution may be any suitable amino acid, including, but not limited to, histidine, glutamine, alanine, aspartic acid, lysine, glycine, cysteine, arginine, proline, or combinations thereof.

The first persulfate of the antiseptic mixture, when present, and the second persulfate of the reaction solution of the antiseptic polymer, when present, may be any suitable persulfate, including, but not limited to, peroxomonosulfate. Suitable peroxomonosulfates include, but are not limited to, LiHSO₅, NaHSO₅, KHSO₅, LiNaSO₅, LiKSO₅, NaKSO₅, Li₂SO₅, Na₂SO₅, K₂SO₅, or combinations thereof.

The aforementioned first sulfates of the antiseptic mixture and first persulfates of the antiseptic mixture may be combined with one another in any combination. In one embodiment, the first sulfate includes K₂SO₄ and the first persulfate includes KHSO₅. In a further embodiment, the first sulfate consists of K₂SO₄ and the first persulfate consists of KHSO₅.

The aforementioned second sulfates, second persulfates, and amino acids of the reaction solution of the antiseptic polymer may be combined with one another in any suitable combination. In one embodiment, the second sulfate of the reaction solution includes K₂SO₄, the second persulfate of the reaction solution includes KHSO₅, and the amino acid of the reaction solution includes histidine. In a further embodiment, the second sulfate of the reaction solution consists of K₂SO₄, the second persulfate of the reaction solution consists of KHSO₅, and the amino acid of the reaction solution consists of histidine.

In one embodiment, the antiseptic composition includes both the antiseptic mixture and the antiseptic polymer. The second sulfate of the reaction solution of the antiseptic polymer may have the same chemical composition as the first sulfate of the antiseptic mixture or a distinct composition from the first sulfate of the antiseptic mixture. The second persulfate of the reaction solution of the antiseptic polymer may have the same chemical composition as the first persulfate of the antiseptic mixture or a distinct composition from the first persulfate of the antiseptic mixture. The first sulfate of the antiseptic mixture and the second sulfate of the reaction solution of the antiseptic polymer may have the same chemical composition while the first persulfate of the antiseptic mixture and the second persulfate of the reaction solution of the antiseptic polymer have distinct chemical compositions from one another. Alternatively, the first persulfate of the antiseptic mixture and the second persulfate of the reaction solution of the antiseptic polymer may have the same chemical composition while the first sulfate of the antiseptic mixture and the second sulfate of the reaction solution of the antiseptic polymer have distinct chemical compositions from one another. Alternatively, first persulfate of the antiseptic mixture and the second persulfate of the reaction solution of the antiseptic polymer may have the same chemical composition while the first sulfate of the antiseptic mixture and the second sulfate of the reaction solution of the antiseptic polymer have the same chemical composition.

The antiseptic mixture may be formed by dissolving a triple salt in a suitable solvent, such as, but not limited to, water, to form a solution, acid titrating the solution, performing solvent extraction on the solution, and then filtering the solution. Precipitate formed during this process may be dried to yield the antiseptic mixture in crystalline form. This antiseptic mixture in crystalline form may be used, directly applied as a solid or dissolved in a solvent to form an antiseptic irrigation solution. The remaining solution following recovery of the antiseptic mixture in crystalline form, which has a composition distinct from the dissolved triple salt, may be reacted with amino acid to form the antiseptic polymer. This antiseptic polymer may itself be used in its amorphous form or may be suspended in a solvent to form an antiseptic irrigation solution.

In one embodiment, an antiseptic irrigation solution includes a stabilized active oxygen-generating antiseptic composition and a solvent in which the stabilized active oxygen-generating antiseptic composition is dispersed. The antiseptic composition includes at least one of an antiseptic dispersal of the antiseptic mixture or the antiseptic polymer. With respect to the antiseptic dispersal of the antiseptic mixture, it is noted that the antiseptic dispersal would have the first sulfate and the first persulfate characterized by a ratio of the first sulfate to the first persulfate of at least 8:2, and as further described above, but that, as dispersed, the first sulfate may no longer constitute a matrix in which the first persulfate is distributed. In a further embodiment, the antiseptic composition includes both the antiseptic dispersal of the antiseptic mixture (the first sulfate and the first persulfate) as well as the antiseptic polymer.

Suitable solvents include, but are not limited to, water, aqueous solutions, biological fluids, wound exudate, blood plasma, or combinations thereof.

The concentration of the combined first sulfate and first persulfate in the solvent may be any suitable concentration, including, but not limited to, 0.01-100 mg/mL, alternatively 0.1-75 mg/mL, alternatively 0.1-10 mg/mL, alternatively 5-15 mg/mL, alternatively 10-20 mg/mL, alternatively 15-25 mg/mL, alternatively 20-30 mg/mL, alternatively 25-35 mg/mL, alternatively 30-40 mg/mL, alternatively 35-45 mg/mL, alternatively 40-50 mg/mL, alternatively 45-55 mg/mL, alternatively 50-60 mg/mL, alternatively 55-65 mg/mL, alternatively 60-70 mg/mL, alternatively 65-75 mg/mL, alternatively 70-80 mg/mL, alternatively 75-85 mg/mL, alternatively 80-90 mg/mL, alternatively 85-95 mg/mL, alternatively 90-100 mg/mL, or combinations or subdivisions thereof.

The antiseptic irrigation solution may have any suitable pH, including, but not limited to, a pH of 2.0-7.0; alternatively 2.5-6.5, alternatively 2.5-3.5, alternatively 3.0-4.0, alternatively 3.5-4.5, alternatively 4.0-5.0, alternatively 4.5-5.5, alternatively 5.0-6.0, alternatively 5.5-6.5, or combinations or subdivisions thereof.

The antiseptic irrigation solution may produce active oxygen for any suitable length of time following solvation of the antiseptic composition by the solvent, including, but not limited to, a period of at least 72 hours. In one embodiment, the antiseptic irrigation solution may produce active oxygen at a concentration of 0.01-1% based on the total antiseptic composition, alternatively 0.01-0.1%, alternatively 0.05-0.15%, alternatively 0.1-0.2%, alternatively 0.15-0.25%, alternatively 0.2-0.3%, alternatively 0.25-0.35%, alternatively 0.3-0.4%, alternatively 0.35-0.45%, alternatively 0.3-0.4%, alternatively 0.35-0.45%, alternatively 0.4-0.5%, alternatively 0.45-0.55%, alternatively 0.5-0.6%, alternatively 0.55-0.65%, alternatively 0.6-0.7%, alternatively 0.65-0.75%, alternatively 0.7-0.8%, alternatively 0.75-0.85%, alternatively 0.8-0.9%, alternatively 0.85-0.95%, alternatively 0.9-1%, alternatively 0.1%, or combinations or subdivisions thereof.

In one embodiment, the antiseptic composition produces active oxygen at a lower rate and for a longer time than a comparative antiseptic irrigation solution having an equal amount (molar) of potassium peroxymonosulfate triple salt in lieu of the antiseptic composition and being otherwise identical.

The active oxygen produced by the antiseptic composition may include singlet 02, ozone, superoxide, peroxide, or combinations thereof.

The antiseptic composition may further include amino acid dispersed in the solvent. Suitable amino acids which may be employed include, but are not limited to, histidine, glutamine, alanine, aspartic acid, lysine, glycine, cysteine, arginine, proline, or combinations thereof. The amino acid may be present at any suitable concentration, including, but not limited to, a concentration (based on the total antiseptic composition) of lmg/mL up to the solubility limit of the amino acid or amino acids dispersed therein, or combinations or subdivisions thereof.

In one embodiment, wherein the antiseptic composition including the antiseptic polymer rather than the antiseptic dispersal produces active oxygen at a lower rate and for a longer time relative to the antiseptic composition including the antiseptic dispersal rather than the antiseptic polymer at equal amounts (molar) the first sulfate to the second sulfate and the first persulfate to the second persulfate and being otherwise identical.

The stabilized oxygen-generating antiseptic compositions and antiseptic irrigation solutions disclosed herein may be used to treat surgical wounds, burns, lacerations, diabetic wounds, combat wounds, acute wounds, chronic wounds, and any other suitable wounds. The stabilized oxygen-generating antiseptic compositions may be applied directly to the wounds in particulate form or suspended in a suitable medium and may interact with biological fluids such as wound exudate and/or blood plasma to release active oxygen at a predetermined rate. Dissolved oxygen present in the antiseptic irrigation solutions may be released within the wound/operative site due to a change in pH (e.g. the antiseptic irrigation solution may have a pH of 4.0 whereas the wound bed would typically have an environmental pH of 6.5-7.0), altering the chemical equilibrium of the antiseptic irrigation solutions and releasing active oxygen to the wound tissue.

Without being bound by theory, it is noted that microbes produce a biofilm matrix including bacterial extracellular polysaccharide polymer protecting the bacteria within, and it is believed that the active oxygen produced by the stabilized oxygen-generating antiseptic compositions and antiseptic irrigation solutions formed therefrom depolymerize the biofilm protecting polysaccharide polymer structure by selective oxidation of glycosidic linkages to form glucose monomer and eradicate the bacteria within the biofilm. A mechanism for the oxidation of the glycosidic linkages in the polysaccharides is shown in FIG. 1 .

In one embodiment, the bacteria, fungi, and viruses, against which the stabilized oxygen-generating antiseptic compositions and antiseptic irrigation solutions are effective, include Staphylococcus Aureus (MRSA), Salmonella typhimurium, Pseudomonas aeruginosa, Klebsiella pneumonia, Acinetobacter baumannii, Escherichia coli, Enterococcus faecium, Enterobacter cloacae, Enterovacter aerogenes, Corynebacterium, pseudodiptherium, Corynebacterium pseudodiptherium, Candida albicans, and Hepatitis A virus (HAv).

In one embodiment, an antiseptic article includes an article (having a surface) and at least one of a stabilized active oxygen-generating antiseptic composition or an oxygen-generating antiseptic coating formed from the stabilized active oxygen-generating antiseptic composition disposed on the surface of the article. The stabilized active oxygen-generating antiseptic composition includes at least one of the antiseptic mixture or the antiseptic polymer (both as further described above). The antiseptic article may include both the stabilized active oxygen-generating antiseptic composition and the oxygen-generating antiseptic coating formed from the stabilized active oxygen-generating antiseptic composition disposed on the surface of the article. The stabilized active oxygen-generating antiseptic composition may include both the antiseptic mixture and the antiseptic polymer.

The surface of the article on which the stabilized active oxygen-generating antiseptic composition, the oxygen-generating antiseptic coating formed from the stabilized active oxygen-generating antiseptic composition, or both is disposed may be an external surface of the article or an internal surface of the article, or both. In one embodiment, wherein the article includes a continuous porous substrate, the internal surface of the article on which the stabilized active oxygen-generating antiseptic composition, the oxygen-generating antiseptic coating formed from the stabilized active oxygen-generating antiseptic composition, or both is disposed is an internal continuous surface of the continuous porous substrate in fluid communication with an external surface of the article.

The oxygen-generating antiseptic coating may be covalently bonded, ionically bonded, or both to the surface of the article. The oxygen-generating antiseptic coating may be a monolayer or may have a plurality of layers.

In one embodiment, the stabilized active oxygen-generating antiseptic composition is applied to the surface of an article forming a monolayer coating that at least partially coats the article surface. Without being bound by theory, it is believed that the molecules on the monolayer coating have covalent or ionic or mixed chemical bonding characteristics under room temperature drying to form and adhere the monolayer coating to the implant surface. The level or degree of active molecule attachment may depend upon the properties and characteristics of the article surface (e.g., whether the surface is treated or untreated). In a further embodiment, the article surface undergoes a treatment that enhances or improves bonding and/or adherence of the stabilized active oxygen-generating antiseptic composition to the article surface. The treatment may be applied during manufacture or sterilization of the article. Suitable treatments include, but are not limited to, various treatments for enhancing the adherence or attachment of a coating to an uncoated surface, such as, but not limited to, gamma ray exposure.

The stabilized active oxygen-generating antiseptic composition in the form of a monolayer coating may be applied to the surface of an article using conventional coating techniques and apparatuses. Suitable coating techniques for use in the in the invention include, but are not limited to, dipping, brushing, and spraying. In one embodiment, an article is dipped into a solution of the stabilized active oxygen-generating antiseptic composition to form a monolayer coating on the article surface, and then the coated article is dried. Suitable drying techniques include, but are not limited to, conventional techniques and apparatuses for drying compositions applied to a substrate surface to form a coating. Dip-coating and then drying the coated article in a furnace and ambient atmosphere and pressure may produce a monolayer coating exhibiting improved antimicrobial properties relative to a monolayer coating produced without drying in a furnace. Without intending to be bound by theory, it is believed that use of a thermal activation process enhances the bonding of the monolayer to the article and yields a more robust monolayer of active molecules on the article surface relative to a process without active drying in a furnace.

The application or deposition of the stabilized active oxygen-generating antiseptic composition to form the monolayer coating and/or the drying process for the monolayer coating on the surface of the article when the article is an implant may be administered prior to, during, or after implantation of the implant into a patient body. In one embodiment, the surface treatment and/or monolayer coating and/or drying process is applied or deposited onto the implant surface while the implant is positioned or located outside of the body (i.e., prior to surgery). In another embodiment, the surface treatment and/or monolayer coating and/or drying process is applied or deposited onto the implant surface while the implant is being positioned/implanted inside of the body (i.e., during surgery). In yet another embodiment, the surface treatment and/or monolayer coating and/or drying process is applied or deposited onto the implant surface after the implant is positioned or located inside of the body, (i.e., following the implantation portion of surgery, but optionally prior to closure of the surgical site when the surgical site does not remain exposed at the completion of the surgery). The surface treatment and/or monolayer coating and/or drying process may be applied or deposited onto the implant surface of an uncoated implant that was previously positioned or located inside of the body (e.g., during a previous surgery) or the surface treatment and/or monolayer coating and/or drying process may be applied or deposited as a subsequent/additional coating (e.g., second coating) onto the implant surface of a coated implant that was previously positioned or located inside of the body (e.g., during a previous surgery).

In addition to the stabilized active oxygen-generating antiseptic compositions and irrigation solutions disclosed herein for use in forming a monolayer coating on the surface of an antiseptic article, there are additional conventional materials that are suitable for use in coating the surface of an antiseptic article such as an antiseptic implant which may be suitable for use in conjunction with the stabilized active oxygen-generating antiseptic compositions and irrigation solutions disclosed herein. Suitable conventional materials include, but are not limited to, antiseptics, disinfectants, germicides, antibacterials, and combinations thereof, such as, but not limited to, chlorhexidine.

Staphylococcus aureus ATCC 43300 (MRSA)

Klebsiella pneumoniae ATCC 13883

Acinetobacter baumannii (clinical isolate)

Pseudomonas aeruginosa ATCC 27853

Enterococcus faecium (VRE clinical isolate)

A stabilized oxygen-generating antiseptic composition was prepared and dissolved at a concentration of 1 mg/mL in aqueous suspensions of cultures at a density of approximately 5×105 cfu/mL. The stabilized oxygen-generating antiseptic composition was characterized by a sulfate to persulfate ration of 9.7:0.3, with the sulfate being K₂SO₄ and the persulfate being KHSO₅. The stabilized oxygen-generating antiseptic composition was free of amino acids, and produced 0.1% active oxygen in the resulting solution, as measured by iodometric titration. At intervals, samples were removed, diluted through D/E neutralizing broth, and spread onto plates of D/E neutralizing agar. Plates were incubated for 24-48 hours at 35° C.

For the Gram-negative cultures, A. baumannii, E. aerogenes, K. pneumoniae, and P. aeruginosa, viable count declined over 15 minutes to where the experiment could not measure it (<100 CFU/mL).

For S. aureus, viable count declined approximately 98% over 30 minutes (in one experiment, from 4.2±0.4×105 cfu/mL to 7.4±1.4×103 cfu/mL). For E. faecium, which was the most tolerant, viable count declined approximately 97% over 30 minutes.

Testing demonstrated successful in-vitro eradication of planktonic and biofilm populations of MRSA and P. aeruginosa. Percent killing and Logio reduction of P. aeruginosa (ATCC 27853) and MRSA (ATCC 35984) biofilms by antiseptic irrigation solution was performed according to Minimum Biofilm Eradication Concentration (MBEC) Assay® protocol. The results of this testing are shown in Table 1.
